This article describes the UDP communication method of PHP Socket communication. Share it with you for your reference. The details are as follows:

1. create a simple UDP server

// Server information $ server = 'udp: // 127.0.0.1: 8080'; // message end symbol $ msg_eof = "\ n"; $ socket = stream_socket_server ($ server, $ errno, $ errstr, STREAM_SERVER_BIND); if (! $ Socket) {die ("$ errstr ($ errno)");} do {// receive information sent from the client $ inMsg = stream_socket_recvfrom ($ socket, 1024, 0, $ peer); // The server prints the relevant information echo "Client: $ peer \ n"; echo "Receive: {$ inMsg }"; // send the message $ outMsg = substr ($ inMsg, 0, (strrpos ($ inMsg, $ msg_eof) to the client ))). '--'. date ("d m j H: I: s Y \ r \ n"); stream_socket_sendto ($ socket, $ outMsg, 0, $ peer);} while ($ inMsg! = False );

2. simple client

function udpGet($sendMsg = '', $ip = '127.0.0.1', $port = '9998'){   $handle = stream_socket_client("udp://{$ip}:{$port}", $errno, $errstr);   if( !$handle ){     die("ERROR: {$errno} - {$errstr}\n");   }   fwrite($handle, $sendMsg."\n");   $result = fread($handle, 1024);   fclose($handle);   return $result; } $result = udpGet('Hello World'); echo $result;
